The FPC syntax for procedure attributes is also available in 
Delphi-mode, but if the modeswitch is there that's fine.

As I said, some people wanted it to be Delphi compatible, other people 
did not mind if it was not. Both categories of people were in the core 
team. There is nevertheless in fact a double standard here, but only in 
the sense of new features vs. existing features: making something 
Delphi-compatible when it is newly introduced does not break anything, 
while changing something that already exists breaks backward compatibility.

Exactly because of that reason, the discussions can be more heated when 
it concerns a new feature, because it is known that it is virtually 
impossible to change later.
